What Causes Teeth Discoloration?

Nobody likes the idea of having stained, discolored teeth. Not only do they greatly impact the visual appeal of your teeth, they can also affect your self-esteem and can be a source of embarrassment.

The discoloration of teeth is a common problem worldwide, encouraging people to seek teeth whitening services.

There are three major types of teeth discoloration—extrinsic (affecting the outer layer of the teth), intrinsic (affecting the inner layer of the teeth), and age-related. The American Association of Orthodontists found that approximately 90 percent of the American population sought teeth whitening services. From brushing and flossing your teeth regularly to avoiding certain foods, it is important for you to protect your pearly whites.

Below we will examine some factors that can cause teeth discoloration:

You’re eating the wrong foods

A major cause of teeth discoloration is the consumption of foods and beverages that have strong colors. These include but are not limited to, coffee, wine, blueberries, blackberries, curry, and tomato sauce. Consider having milk with your coffee to prevent it from staining your teeth, or add vegetables to your meals to avoid staining.

Poor dental hygiene

You can suffer from teeth discoloration if you have unhealthy dental habits. It may sound fairly simple, but brushing and flossing your teeth goes a long way when it comes to protecting your teeth’s natural color. Not doing so leaves food particles and forms harmful bacteria in your mouth that gradually cause your teeth to stain. Therefore, make it a point to brush your teeth regularly.

Teeth Discoloration – Diseases

Many diseases that impact your tooth’s enamel and dentin can cause teeth discoloration. Treatments for particular health conditions can also cause it. For example, head and neck radiation or chemotherapy can greatly impact your teeth and affect their natural color.

Age and genetics

As people age, the outer layer of their teeth enamel tends to wear off. This reveals the inherent yellow color of their dentin. Moreover, the teeth also develops more dentin overtime and gradually reduces the size of the pulp. This greatly decreases the transparency of the tooth, and gives it a darker, more discolored appearance. Genetics also play a role in teeth discoloration, as some inherently have thicker enamel than other people.


You can suffer from teeth discoloration if your teeth have experienced severe trauma from injury or accidents. Injuries make teeth bleed internally and stain the dentin with blood. This eventually discolors or darkens the appearance of the teeth.
